Zero echo time (ZTE) imaging using the RUFIS sequence allows for silent imaging with high efficiency. Without modifications, RUFIS produces proton density and/or T₁-weighted images similar to a spoiled gradient echo sequence. In this work we present a novel T₂-prepared RUFIS sequence with multiple echo times acquired in each shot, for efficient T₂-weighted imaging. We present in vivo results acquired in 11 min with 1.5mm³ resolution, with effective echo times from 0 to 248ms.
